Definitions

  • the invention refers to a clutch system for lower collection casing for roller blind tapes which consists of a case with a cover housing a mechanism encompassing two single internal components: a serrated socket and a strip steel, as well as an external clutch socket where the casing is incorporated.
  • the clutch devices offer different fixing solutions depending on whether the solution chosen is incorporated into the drum of the shaft of the blind roller or inside the lower tape roller case near the lowest level of the extended blind roller.
  • the proposed invention solves both problems by reducing on the one hand the number of components of the clutch system to a minimum number and, on the other hand, by conferring multiple uses to such components.
  • the design of one of the components solves the mechanical problem posed by the tension at the end of the strip steel since an additional intermediate operation during the assembly consisting of a 90 0 turn makes it impossible to detach the strip steel from its fixing point.
  • the clutch operated rolling device for blind roller tapes consists of a metal cylindrical case with a cover.
  • the axis presents a circular bore with the flanges bent inwards and a concentrical outer projection around both bores.
  • a flat head pin normally a rivet, which simultaneously supports the strip steel and the lower end of the rolled tape of the blind roller.
  • This operation prepares the tape in order to tangentially introduce inside it the head of the pin.
  • sufficient space should have been allowed at the rivet or the pin body to house this end of the tape which is thinner than the intermediate part of the pin.
  • This pin once inside the case, is used to fix one of the ends of the strip steel.
  • it incorporates a central slot.
  • the cut made in the middle part of the relevant end has the shape of keyhole so that the pin enters through its circular section and the tension of the strip steel forces the pin to be housed towards the other end of the cut.
  • This strip steel has the peculiarity that it is fixed - without the need for rivets - by the opposite turning end, which also presents a central slot.
  • a tubular socket is used. Two hooks with opposed angles protrude from such tubular socket towards the circumference of the socket.
  • the first operation consists of introducing the longitudinal slot at the end of the strip steel - keeping parallel the diagonal of the slot to the line where theoretically both hooks join after having protected the protrusion of one of them - until its end reaches the butt of the most curved inner part of it. Then, the socket is turned 45 0 with respect to the strip steel so that the longitudinal side of the slot remains perpendicular to the height of the socket and the strip steel is fixed between both hooks.
  • both hooks are made by making a slot in two U-shaped elements with opposed openings in the socket itself, and its thickness is the appropriate one, the tension of the strip steel prevents the deformation of the hook and, therefore, the only possibility of separating both is to repeat the assembly operation described above, following the opposite sequence. This is impossible unless the case is open and the strip steel is deliberately extracted.
  • This hooked socket also incorporates a double serrated layout by means of two wedge-shaped flanges made by cutting and bending its both ends. This cut is located at the orthogonally opposite ends with respect to the point diametrally opposed to that where the hooks are located.
  • the clutch - apart from the clutch socket (1) and the outer shaft reinforcement (9) - consists of the case with cover (2), the pin (3) which fixes the blind roller tape and supports one end of the strip steel (4) and the serrated socket (5) with the fixing hooks (6) and the clutch flanges (7).
